Description

TechInn Noctua Nf-s12a Pwm Fan. The Noctua NF-S12A PWM fan, building on the award-winning S12 legacy, offers enhanced airflow and noise efficiency. Featuring an optimized blade design with Anti-Stall Knobs and the AAO frame, it excels in various impedance situations. The PWM version includes a custom NE-FD1 IC for automatic speed control, and a Low-Noise Adaptor for quieter operation. With its superb running smoothness, SSO2 bearing, and premium quality, it´s an elite choice for silent PC cooling. The NF-S12A marks the third generation of Noctua's signature S12 series quiet case fans, which have received more than 250 awards and recommendations from the international press. Featuring a further refined blade design with Anti-Stall Knobs that works in tandem with the new AAO (Advanced Acoustic Optimisation) frame, the NF-S12A improves the airflow/noise efficiency of its renowned predecessor by up to 8%. The PWM version sports Noctua's custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 1200 to 900rpm. Its superb running smoothness, SSO2 bearing and Noctua's trusted premium quality make it an elite choice for quiet case cooling.Features:Award-winning S12 design:- The NF-S12A features the third evolution of Noctu´s classic Straight Blade Design that has earned its S12 series countless recommendations from hardware journalists and enthusiasts around the world. Further optimised for even better airflow/noise efficiency, it makes the NF-S12A an ideal quiet case fan.Anti-Stall Knobs:- The NF-S12´s Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations and thereby increase the fan´s stall margin. This means that the NF-S12A is even more versatile than its renowned predecessor and can achieve better performance on heatsinks and radiators.AAO frame:- Noctu´s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctu´s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan´s performance/noise efficiency.Stepped Inlet Design:- Noctu´s Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space-restricted environments.Inner Surface Microstructures:- With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.Integrated anti-vibration pads:- Integrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.Custom-designed PWM IC with SCD:- Supporting fully automatic PWM speed control, the NF-S12A PWM uses Noctu´s novel, custom-designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds.Stops at 0% PWM:- When the fan is set to 0% PWM duty cycle by the motherboard or PWM fan controller, it will stop. This makes it ideal for creating setups with semi-passive cooling that automatically turn the fans off and thus run completely silent at idle if thermals allow.Low-Noise Adaptor:- The NF-S12A PWM is supplied with a (L.N.A.) that reduces the maximum fan speed from 1200 to 900rpm. The L.N.A. can be used either to run the fan at a fixed speed of 900rpm or to cap the maximum speed when using automatic PWM control.Extensive cabling options:- The fan´s short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows the connection of a second fan to the same PWM fan header for automatic control.SSO2 Bearing:- The NF-S12A features the further optimised second generation of Noctu´s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability.Metal bearing shell:- In order to the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability, the NF-S12A sports a CNC milled bearing shell made entirely from brass.NE-FD1 PWM IC:- Noctu´s custom-designed NE-FD1 is a next-generation PWM fan driver IC that integrates Smooth Commutation Drive (SCD) technology for quieter operation and allows for ultra-low power consumption. Its superb linearity and security features such as locked rotor or reverse voltage protection make it an ideal driver IC for premium-class PWM fans.- Most conventional PWM fan driver ICs put out square signals that cause sudden torque impulses. These impulses can cause minute deformations of the entire fan structure which lead to audible ´´clicking´´ noises that are especially noticeable with many common PWM fans running at slower speeds. Adopting Noctu´s Smooth Commutation Drive (SCD) technology, the custom designed NE-FD1 PWM IC slows down the slew rate of the output signal in order to give a smoother, less sudden torque impulse. This way, PWM switching noises can be effectively suppressed and the fan runs even quieter, especially at low speeds.- Noctu´s NE-FD1 IC was not only fine-tuned for superior quietness, it has also been carefully optimised to allow for ultra-low power consumption. For example, the NE-FD1 based PWM version of the award-winning NF-R8, NF-B9 and NF-P12 fans consume 25-40% less power than their non-PWM counterparts. The NF-F12 120mm fan featuring the NE-FD1 IC draws only 0.6W, which is more than 50% less than many fans in the same speed range. This doesn´t only make it eco-friendly but also cuts down the electricity bill: Compared to a typical 2W fan, this allows you to save about half the price of the NF-F12 after 5 years of continuous use.Specifications:FAN:- Size: 120x120x25 mm- Mounting hole spacing: 105x105 mm- Connector & pin-configuration: 4-pin PWM- Cable length: 20cm + 30cm NA-EC1 extension cable- Bearing: SSO2- Blade geometry: S-Series with Anti-Stall Knobs- Frame technology: AAO (Advanced Acoustic Optimisation)- Rotational speed (+/- 10%): 1200 RPM- Rotational speed with L.N.A.
